[0029] The spindle 200 includes an external spindle connection 210 and an internal spindle connection 220 connected to the external spindle connection 210;

[0030] The bushing 300 includes a first bushing 310 and a second bushing 320. The transmission panel 100, the main shaft 200, and the first bushing 310 are coaxially distributed. The first bushing 310 and the second bushing 320 are not coaxially distributed. The first bushing 310 is located between the inner part 220 of the main shaft and the second bushing 320 (equivalent to the inner part 220 of the main shaft being connected to the first bushing 310 and being coaxially distributed relative to the first bushing 310, and the first bushing 310 being connected to the second bushing 320 and being not coaxially distributed relative to the second bushing 320). The transmission panel 100 and the back plate 400 together form an inner cavity (not shown in the figure) for accommodating the inner part 220 of the main shaft, the first bushing 310, and the second bushing 320. The outer part 210 of the main shaft is externally placed on the transmission panel 100. This allows the hydraulic oil pump transmission mechanism to form an eccentric transmission inside the transmission panel 100, thereby generating radial reciprocating motion and realizing the output function of the hydraulic oil pump.

[0031] The transmission panel 100 has a spindle through hole 110, and the spindle inner connection part 220 is connected to the spindle through hole 110. The transmission panel 100 also has several irregular grooves and several irregular through holes. The irregular grooves and irregular through holes are asymmetrically distributed relative to the spindle through hole 100 to assist the spindle outer connection part 210 in positioning and connecting to other structures.

[0032] The irregular through holes include a first through hole 120 and a second through hole 130. The first through hole 120 and the second through hole 130 are respectively distributed on the side of the transmission panel 100 away from the back plate 400. The first through hole 120 and the second through hole 130 are not connected (there is a gap between them).

[0033] The irregular groove includes a first groove 140, a second groove 150 and a third groove 160. The first groove 140, the second groove 150 and the third groove 160 are respectively distributed on the side of the transmission panel 100 away from the back plate 400. The first groove 140, the second groove 150 and the third groove 160 are not connected to each other (there is a gap).

[0034] Among them, irregular through holes and irregular grooves are distributed around the outer surface of the transmission panel 100 relative to the main shaft through hole 110.

[0035] The transmission panel 100 also has two panel positioning holes 170, which are symmetrically distributed relative to the spindle through hole 110.

[0036] The back plate 400 includes a back plate body 410 and two back plate screws 420. The back plate body 410 is detachably connected to the transmission panel 100 via the back plate screws 420.

[0037] Preferably, the spindle through hole 110 is located at the center of the transmission panel 100.

[0038] Preferably, the outer surface of the spindle external connection 210 is provided with a spline structure.

[0039] Preferably, both the irregular through-hole and the irregular groove are elongated.

[0040] As further explanation, in the hydraulic pump transmission mechanism disclosed in this embodiment, the inner shaft connection 220 is connected to the first bushing 310 and coaxially distributed relative to the first bushing 310. The first bushing 310 is connected to the second bushing 320 and non-coaxially distributed relative to the second bushing 320. This allows the main shaft 200 to drive the bushing 300 to produce radial reciprocating motion during rotation, thereby realizing the output function of the hydraulic pump. The entire transmission mechanism is compact in structure and reliable in operation, and is a key transmission component of the hydraulic system.

[0041] It is worth mentioning that the specific material and other technical features of the first bushing 310 involved in this utility model patent application should be regarded as prior art.
